Automatic scope configuration of monitoring agents for tracking missing events at runtime

ABSTRACT

In one embodiment, a device receives, from a monitoring agent that monitors an application, an indication that the monitoring agent did not capture information regarding a particular event during execution of the application. The device determines that the particular event is of a relevant event type that should be tracked. The device generates a configuration for the monitoring agent that adjusts a monitoring scope of the monitoring agent so as to capture information regarding the particular event. The device causes the monitoring agent to be updated with the configuration, wherein the monitoring agent captures information regarding the particular event after being updated with the configuration.

TECHNICAL FIELD

The present disclosure relates generally to computer systems, and, moreparticularly, to automatic scope configuration of monitoring agentstracking missing events at runtime.

BACKGROUND

The Internet and the World Wide Web have enabled the proliferation ofweb services available for virtually all types of businesses. Due to theaccompanying complexity of the infrastructure supporting the webservices, it is becoming increasingly difficult to maintain the highestlevel of service performance and user experience to keep up with theincrease in web services. For example, it can be challenging to piecetogether monitoring and logging data across disparate systems, tools,and layers in a network architecture. Moreover, even when data can beobtained, it is difficult to directly connect the chain of events andcause and effect.

In general, application performance monitoring (APM) seeks to measurethe performance of a remote-hosted application, such as a cloud-hostedapplication. Today, the majority of APM solutions define the rules andconfigurations based on certain logic with no insight into the userapplications. So, tracking the runtime behavior of an applicationoutside of its defined scope becomes tedious because doing so warrantsmanual intervention and/or additional rules/configurations. In otherwords, APM today is typically performed using predetermined scopedefinitions in the hope that events of interest occur within the scopeof the monitoring. This can lead to information regarding events such asexit calls, exceptions, and the like, being missed.

DESCRIPTION

A computer network is a geographically distributed collection of nodesinterconnected by communication links and segments for transporting databetween end nodes, such as personal computers and workstations, or otherdevices, such as sensors, etc. Many types of networks are available,ranging from local area networks (LANs) to wide area networks (WANs).LANs typically connect the nodes over dedicated private communicationslinks located in the same general physical location, such as a buildingor campus. WANs, on the other hand, typically connect geographicallydispersed nodes over long-distance communications links, such as commoncarrier telephone lines, optical lightpaths, synchronous opticalnetworks (SONET), synchronous digital hierarchy (SDH) links, orPowerline Communications (PLC), and others. The Internet is an exampleof a WAN that connects disparate networks throughout the world,providing global communication between nodes on various networks. Othertypes of networks, such as field area networks (FANs), neighborhood areanetworks (NANs), personal area networks (PANs), enterprise networks,etc. may also make up the components of any given computer network.

The nodes typically communicate over the network by exchanging discreteframes or packets of data according to predefined protocols, such as theTransmission Control Protocol/Internet Protocol (TCP/IP). In thiscontext, a protocol consists of a set of rules defining how the nodesinteract with each other. Computer networks may be furtherinterconnected by an intermediate network node, such as a router, toextend the effective “size” of each network.

Smart object networks, such as sensor networks, in particular, are aspecific type of network having spatially distributed autonomous devicessuch as sensors, actuators, etc., that cooperatively monitor physical orenvironmental conditions at different locations, such as, e.g.,energy/power consumption, resource consumption (e.g., water/gas/etc. foradvanced metering infrastructure or “AMI” applications) temperature,pressure, vibration, sound, radiation, motion, pollutants, etc. Othertypes of smart objects include actuators, e.g., responsible for turningon/off an engine or perform any other actions. Sensor networks, a typeof smart object network, are typically shared-media networks, such aswireless or power-line communication networks. That is, in addition toone or more sensors, each sensor device (node) in a sensor network maygenerally be equipped with a radio transceiver or other communicationport, a microcontroller, and an energy source, such as a battery.Generally, size and cost constraints on smart object nodes (e.g.,sensors) result in corresponding constraints on resources such asenergy, memory, computational speed and bandwidth.

FIG. 1A is a schematic block diagram of an example computer network 100illustratively comprising nodes/devices, such as a plurality ofrouters/devices interconnected by links or networks, as shown. Forexample, customer edge (CE) routers 110 may be interconnected withprovider edge (PE) routers 120 (e.g., PE-1, PE-2, and PE-3) in order tocommunicate across a core network, such as an illustrative networkbackbone 130. For example, routers 110, 120 may be interconnected by thepublic Internet, a multiprotocol label switching (MPLS) virtual privatenetwork (VPN), or the like. Data packets 140 (e.g., traffic/messages)may be exchanged among the nodes/devices of the computer network 100over links using predefined network communication protocols such as theTransmission Control Protocol/Internet Protocol (TCP/IP), User DatagramProtocol (UDP), Asynchronous Transfer Mode (ATM) protocol, Frame Relayprotocol, or any other suitable protocol. Those skilled in the art willunderstand that any number of nodes, devices, links, etc. may be used inthe computer network, and that the view shown herein is for simplicity.

In some implementations, a router or a set of routers may be connectedto a private network (e.g., dedicated leased lines, an optical network,etc.) or a virtual private network (VPN), such as an MPLS VPN thanks toa carrier network, via one or more links exhibiting very differentnetwork and service level agreement characteristics.

FIG. 1B illustrates an example of network 100 in greater detail,according to various embodiments. As shown, network backbone 130 mayprovide connectivity between devices located in different geographicalareas and/or different types of local networks. For example, network 100may comprise local/branch networks 160, 162 that include devices/nodes10-16 and devices/nodes 18-20, respectively, as well as a datacenter/cloud environment 150 that includes servers 152-154. Notably,local networks 160-162 and data center/cloud environment 150 may belocated in different geographic locations. Servers 152-154 may include,in various embodiments, any number of suitable servers or othercloud-based resources. As would be appreciated, network 100 may includeany number of local networks, data centers, cloud environments,devices/nodes, servers, etc.

In some embodiments, the techniques herein may be applied to othernetwork topologies and configurations. For example, the techniquesherein may be applied to peering points with high-speed links, datacenters, etc. Furthermore, in various embodiments, network 100 mayinclude one or more mesh networks, such as an Internet of Thingsnetwork. Loosely, the term “Internet of Things” or “IoT” refers touniquely identifiable objects (things) and their virtual representationsin a network-based architecture. In particular, the next frontier in theevolution of the Internet is the ability to connect more than justcomputers and communications devices, but rather the ability to connect“objects” in general, such as lights, appliances, vehicles, heating,ventilating, and air-conditioning (HVAC), windows and window shades andblinds, doors, locks, etc. The “Internet of Things” thus generallyrefers to the interconnection of objects (e.g., smart objects), such assensors and actuators, over a computer network (e.g., via IP), which maybe the public Internet or a private network.

Notably, shared-media mesh networks, such as wireless networks, areoften on what is referred to as Low-Power and Lossy Networks (LLNs),which are a class of network in which both the routers and theirinterconnect are constrained: LLN routers typically operate withconstraints, e.g., processing power, memory, and/or energy (battery),and their interconnects are characterized by, illustratively, high lossrates, low data rates, and/or instability. LLNs are comprised ofanything from a few dozen to thousands or even millions of LLN routers,and support point-to-point traffic (between devices inside the LLN),point-to-multipoint traffic (from a central control point such at theroot node to a subset of devices inside the LLN), andmultipoint-to-point traffic (from devices inside the LLN towards acentral control point). Often, an IoT network is implemented with anLLN-like architecture. For example, as shown, local network 160 may bean LLN in which CE-2 operates as a root node for nodes/devices 10-16 inthe local mesh, in some embodiments.

FIG. 2 is a schematic block diagram of an example computing device(e.g., apparatus) 200 that may be used with one or more embodimentsdescribed herein, e.g., as any of the devices shown in FIGS. 1A-1Babove, and particularly as specific devices as described further below.The device may comprise one or more network interfaces 210 (e.g., wired,wireless, etc.), at least one processor 220, and a memory 240interconnected by a system bus 250, as well as a power supply 260 (e.g.,battery, plug-in, etc.).

The network interface(s) 210 contain the mechanical, electrical, andsignaling circuitry for communicating data over links coupled to thenetwork 100, e.g., providing a data connection between device 200 andthe data network, such as the Internet. The network interfaces may beconfigured to transmit and/or receive data using a variety of differentcommunication protocols. For example, interfaces 210 may include wiredtransceivers, wireless transceivers, cellular transceivers, or the like,each to allow device 200 to communicate information to and from a remotecomputing device or server over an appropriate network. The same networkinterfaces 210 also allow communities of multiple devices 200 tointerconnect among themselves, either peer-to-peer, or up and down ahierarchy. Note, further, that the nodes may have two different types ofnetwork connections via network interface(s) 210, e.g., wireless andwired/physical connections, and that the view herein is merely forillustration. Also, while network interface(s) 210 are shown separatelyfrom power supply 260, for devices using powerline communication (PLC)or Power over Ethernet (PoE), the network interface 210 may communicatethrough the power supply 260, or may be an integral component of thepower supply.

The memory 240 comprises a plurality of storage locations that areaddressable by the processor 220 and the network interfaces 210 forstoring software programs and data structures associated with theembodiments described herein. The processor 220 may comprise hardwareelements or hardware logic adapted to execute the software programs andmanipulate the data structures 245. An operating system 242, portions ofwhich are typically resident in memory 240 and executed by theprocessor, functionally organizes the device by, among other things,invoking operations in support of software processes and/or servicesexecuting on the device. These software processes and/or services maycomprise one or more functional processes 246, and on certain devices,an illustrative monitoring process 248, as described herein. Notably,functional processes 246, when executed by processor(s) 220, cause eachparticular device 200 to perform the various functions corresponding tothe particular device's purpose and general configuration. For example,a router would be configured to operate as a router, a server would beconfigured to operate as a server, an access point (or gateway) would beconfigured to operate as an access point (or gateway), a client devicewould be configured to operate as a client device, and so on.

It will be apparent to those skilled in the art that other processor andmemory types, including various computer-readable media, may be used tostore and execute program instructions pertaining to the techniquesdescribed herein. Also, while the description illustrates variousprocesses, it is expressly contemplated that various processes may beembodied as modules configured to operate in accordance with thetechniques herein (e.g., according to the functionality of a similarprocess). Further, while the processes have been shown separately, thoseskilled in the art will appreciate that processes may be routines ormodules within other processes.

Application Intelligence Platform

The embodiments herein relate to an application intelligence platformfor application performance management. In one aspect, as discussed withrespect to FIGS. 3-5 below, performance within a networking environmentmay be monitored, specifically by monitoring applications and entities(e.g., transactions, tiers, nodes, and machines) in the networkingenvironment using agents installed at individual machines at theentities. As an example, applications may be configured to run on one ormore machines (e.g., a customer will typically run one or more nodes ona machine, where an application consists of one or more tiers, and atier consists of one or more nodes). The agents collect data associatedwith the applications of interest and associated nodes and machineswhere the applications are being operated. Examples of the collecteddata may include performance data (e.g., metrics, metadata, etc.) andtopology data (e.g., indicating relationship information). Theagent-collected data may then be provided to one or more servers orcontrollers to analyze the data.

FIG. 3 is a block diagram of an example application intelligenceplatform 300 that can implement one or more aspects of the techniquesherein. The application intelligence platform is a system that monitorsand collects metrics of performance data for an application environmentbeing monitored. At the simplest structure, the application intelligenceplatform includes one or more agents 310 and one or moreservers/controllers 320. Note that while FIG. 3 shows four agents (e.g.,Agent 1 through Agent 4) communicatively linked to a single controller,the total number of agents and controllers can vary based on a number offactors including the number of applications monitored, how distributedthe application environment is, the level of monitoring desired, thelevel of user experience desired, and so on.

The controller 320 is the central processing and administration serverfor the application intelligence platform. The controller 320 serves abrowser-based user interface (UI) 330 that is the primary interface formonitoring, analyzing, and troubleshooting the monitored environment.The controller 320 can control and manage monitoring of businesstransactions (described below) distributed over application servers.Specifically, the controller 320 can receive runtime data from agents310 (and/or other coordinator devices), associate portions of businesstransaction data, communicate with agents to configure collection ofruntime data, and provide performance data and reporting through theinterface 330. The interface 330 may be viewed as a web-based interfaceviewable by a client device 340. In some implementations, a clientdevice 340 can directly communicate with controller 320 to view aninterface for monitoring data. The controller 320 can include avisualization system 350 for displaying the reports and dashboardsrelated to the disclosed technology. In some implementations, thevisualization system 350 can be implemented in a separate machine (e.g.,a server) different from the one hosting the controller 320.

Notably, in an illustrative Software as a Service (SaaS) implementation,a controller instance may be hosted remotely by a provider of theapplication intelligence platform 300. In an illustrative on-premises(On-Prem) implementation, a controller instance may be installed locallyand self-administered.

The controllers 320 receive data from different agents 310 (e.g., Agents1-4) deployed to monitor applications, databases and database servers,servers, and end user clients for the monitored environment. Any of theagents 310 can be implemented as different types of agents with specificmonitoring duties. For example, application agents may be installed oneach server that hosts applications to be monitored. Instrumenting anagent adds an application agent into the runtime process of theapplication.

Database agents, for example, may be software (e.g., a Java program)installed on a machine that has network access to the monitoreddatabases and the controller. Database agents query the monitoreddatabases in order to collect metrics and pass those metrics along fordisplay in a metric browser (e.g., for database monitoring and analysiswithin databases pages of the controller's UI 330). Multiple databaseagents can report to the same controller. Additional database agents canbe implemented as backup database agents to take over for the primarydatabase agents during a failure or planned machine downtime. Theadditional database agents can run on the same machine as the primaryagents or on different machines. A database agent can be deployed ineach distinct network of the monitored environment. Multiple databaseagents can run under different user accounts on the same machine.

Standalone machine agents, on the other hand, may be standalone programs(e.g., standalone Java programs) that collect hardware-relatedperformance statistics from the servers (or other suitable devices) inthe monitored environment. The standalone machine agents can be deployedon machines that host application servers, database servers, messagingservers, Web servers, etc. A standalone machine agent has an extensiblearchitecture (e.g., designed to accommodate changes).

End user monitoring (EUM) may be performed using browser agents andmobile agents to provide performance information from the point of viewof the client, such as a web browser or a mobile native application.Through EUM, web use, mobile use, or combinations thereof (e.g., by realusers or synthetic agents) can be monitored based on the monitoringneeds. Notably, browser agents (e.g., agents 310) can include Reportersthat report monitored data to the controller.

Monitoring through browser agents and mobile agents are generally unlikemonitoring through application agents, database agents, and standalonemachine agents that are on the server. In particular, browser agents maygenerally be embodied as small files using web-based technologies, suchas JavaScript agents injected into each instrumented web page (e.g., asclose to the top as possible) as the web page is served, and areconfigured to collect data. Once the web page has completed loading, thecollected data may be bundled into a beacon and sent to an EUMprocess/cloud for processing and made ready for retrieval by thecontroller. Browser real user monitoring (Browser RUM) provides insightsinto the performance of a web application from the point of view of areal or synthetic end user. For example, Browser RUM can determine howspecific Ajax or iframe calls are slowing down page load time and howserver performance impact end user experience in aggregate or inindividual cases.

A mobile agent, on the other hand, may be a small piece of highlyperformant code that gets added to the source of the mobile application.Mobile RUM provides information on the native mobile application (e.g.,iOS or Android applications) as the end users actually use the mobileapplication. Mobile RUM provides visibility into the functioning of themobile application itself and the mobile application's interaction withthe network used and any server-side applications with which the mobileapplication communicates.

Application Intelligence Monitoring: The disclosed technology canprovide application intelligence data by monitoring an applicationenvironment that includes various services such as web applicationsserved from an application server (e.g., Java virtual machine (JVM),Internet Information Services (IIS), Hypertext Preprocessor (PHP) Webserver, etc.), databases or other data stores, and remote services suchas message queues and caches. The services in the applicationenvironment can interact in various ways to provide a set of cohesiveuser interactions with the application, such as a set of user servicesapplicable to end user customers.

Application Intelligence Modeling: Entities in the applicationenvironment (such as the JBoss service, MQSeries modules, and databases)and the services provided by the entities (such as a login transaction,service or product search, or purchase transaction) may be mapped to anapplication intelligence model. In the application intelligence model, abusiness transaction represents a particular service provided by themonitored environment. For example, in an e-commerce application,particular real-world services can include a user logging in, searchingfor items, or adding items to the cart. In a content portal, particularreal-world services can include user requests for content such assports, business, or entertainment news. In a stock trading application,particular real-world services can include operations such as receivinga stock quote, buying, or selling stocks.

Business Transactions: A business transaction representation of theparticular service provided by the monitored environment provides a viewon performance data in the context of the various tiers that participatein processing a particular request. A business transaction, which mayeach be identified by a unique business transaction identification (ID),represents the end-to-end processing path used to fulfill a servicerequest in the monitored environment (e.g., adding items to a shoppingcart, storing information in a database, purchasing an item online,etc.). Thus, a business transaction is a type of user-initiated actionin the monitored environment defined by an entry point and a processingpath across application servers, databases, and potentially many otherinfrastructure components. Each instance of a business transaction is anexecution of that transaction in response to a particular user request(e.g., a socket call, illustratively associated with the TCP layer). Abusiness transaction can be created by detecting incoming requests at anentry point and tracking the activity associated with request at theoriginating tier and across distributed components in the applicationenvironment (e.g., associating the business transaction with a 4-tupleof a source IP address, source port, destination IP address, anddestination port). A flow map can be generated for a businesstransaction that shows the touch points for the business transaction inthe application environment. In one embodiment, a specific tag may beadded to packets by application specific agents for identifying businesstransactions (e.g., a custom header field attached to a hypertexttransfer protocol (HTTP) payload by an application agent, or by anetwork agent when an application makes a remote socket call), such thatpackets can be examined by network agents to identify the businesstransaction identifier (ID) (e.g., a Globally Unique Identifier (GUID)or Universally Unique Identifier (UUID)).

Performance monitoring can be oriented by business transaction to focuson the performance of the services in the application environment fromthe perspective of end users. Performance monitoring based on businesstransactions can provide information on whether a service is available(e.g., users can log in, check out, or view their data), response timesfor users, and the cause of problems when the problems occur.

A business application is the top-level container in the applicationintelligence model. A business application contains a set of relatedservices and business transactions. In some implementations, a singlebusiness application may be needed to model the environment. In someimplementations, the application intelligence model of the applicationenvironment can be divided into several business applications. Businessapplications can be organized differently based on the specifics of theapplication environment. One consideration is to organize the businessapplications in a way that reflects work teams in a particularorganization, since role-based access controls in the Controller UI areoriented by business application.

A node in the application intelligence model corresponds to a monitoredserver or JVM in the application environment. A node is the smallestunit of the modeled environment. In general, a node corresponds to anindividual application server, JVM, or Common Language Runtime (CLR) onwhich a monitoring Agent is installed. Each node identifies itself inthe application intelligence model. The Agent installed at the node isconfigured to specify the name of the node, tier, and businessapplication under which the Agent reports data to the Controller.

Business applications contain tiers, the unit in the applicationintelligence model that includes one or more nodes. Each node representsan instrumented service (such as a web application). While a node can bea distinct application in the application environment, in theapplication intelligence model, a node is a member of a tier, which,along with possibly many other tiers, make up the overall logicalbusiness application.

Tiers can be organized in the application intelligence model dependingon a mental model of the monitored application environment. For example,identical nodes can be grouped into a single tier (such as a cluster ofredundant servers). In some implementations, any set of nodes, identicalor not, can be grouped for the purpose of treating certain performancemetrics as a unit into a single tier.

The traffic in a business application flows among tiers and can bevisualized in a flow map using lines among tiers. In addition, the linesindicating the traffic flows among tiers can be annotated withperformance metrics. In the application intelligence model, there maynot be any interaction among nodes within a single tier. Also, in someimplementations, an application agent node cannot belong to more thanone tier. Similarly, a machine agent cannot belong to more than onetier. However, more than one machine agent can be installed on amachine.

A backend is a component that participates in the processing of abusiness transaction instance. A backend is not instrumented by anagent. A backend may be a web server, database, message queue, or othertype of service. The agent recognizes calls to these backend servicesfrom instrumented code (called exit calls). When a service is notinstrumented and cannot continue the transaction context of the call,the agent determines that the service is a backend component. The agentpicks up the transaction context at the response at the backend andcontinues to follow the context of the transaction from there.

Performance information is available for the backend call. For detailedtransaction analysis for the leg of a transaction processed by thebackend, the database, web service, or other application need to beinstrumented.

The application intelligence platform uses both self-learned baselinesand configurable thresholds to help identify application issues. Acomplex distributed application has a large number of performancemetrics and each metric is important in one or more contexts. In suchenvironments, it is difficult to determine the values or ranges that arenormal for a particular metric; set meaningful thresholds on which tobase and receive relevant alerts; and determine what is a “normal”metric when the application or infrastructure undergoes change. Forthese reasons, the disclosed application intelligence platform canperform anomaly detection based on dynamic baselines or thresholds.

The disclosed application intelligence platform automatically calculatesdynamic baselines for the monitored metrics, defining what is “normal”for each metric based on actual usage. The application intelligenceplatform uses these baselines to identify subsequent metrics whosevalues fall out of this normal range. Static thresholds that are tediousto set up and, in rapidly changing application environments,error-prone, are no longer needed.

The disclosed application intelligence platform can use configurablethresholds to maintain service level agreements (SLAs) and ensureoptimum performance levels for system by detecting slow, very slow, andstalled transactions. Configurable thresholds provide a flexible way toassociate the right business context with a slow request to isolate theroot cause.

In addition, health rules can be set up with conditions that use thedynamically generated baselines to trigger alerts or initiate othertypes of remedial actions when performance problems are occurring or maybe about to occur.

For example, dynamic baselines can be used to automatically establishwhat is considered normal behavior for a particular application.Policies and health rules can be used against baselines or other healthindicators for a particular application to detect and troubleshootproblems before users are affected. Health rules can be used to definemetric conditions to monitor, such as when the “average response time isfour times slower than the baseline”. The health rules can be createdand modified based on the monitored application environment.

Examples of health rules for testing business transaction performancecan include business transaction response time and business transactionerror rate. For example, health rule that tests whether the businesstransaction response time is much higher than normal can define acritical condition as the combination of an average response timegreater than the default baseline by 3 standard deviations and a loadgreater than 50 calls per minute. In some implementations, this healthrule can define a warning condition as the combination of an averageresponse time greater than the default baseline by 2 standard deviationsand a load greater than 100 calls per minute. In some implementations,the health rule that tests whether the business transaction error rateis much higher than normal can define a critical condition as thecombination of an error rate greater than the default baseline by 3standard deviations and an error rate greater than 10 errors per minuteand a load greater than 50 calls per minute. In some implementations,this health rule can define a warning condition as the combination of anerror rate greater than the default baseline by 2 standard deviationsand an error rate greater than 5 errors per minute and a load greaterthan 50 calls per minute. These are non-exhaustive and non-limitingexamples of health rules and other health rules can be defined asdesired by the user.

Policies can be configured to trigger actions when a health rule isviolated or when any event occurs. Triggered actions can includenotifications, diagnostic actions, auto-scaling capacity, runningremediation scripts.

Most of the metrics relate to the overall performance of the applicationor business transaction (e.g., load, average response time, error rate,etc.) or of the application server infrastructure (e.g., percentage CPUbusy, percentage of memory used, etc.). The Metric Browser in thecontroller UI can be used to view all of the metrics that the agentsreport to the controller.

In addition, special metrics called information points can be created toreport on how a given business (as opposed to a given application) isperforming. For example, the performance of the total revenue for acertain product or set of products can be monitored. Also, informationpoints can be used to report on how a given code is performing, forexample how many times a specific method is called and how long it istaking to execute. Moreover, extensions that use the machine agent canbe created to report user defined custom metrics. These custom metricsare base-lined and reported in the controller, just like the built-inmetrics.

All metrics can be accessed programmatically using a RepresentationalState Transfer (REST) API that returns either the JavaScript ObjectNotation (JSON) or the eXtensible Markup Language (XML) format. Also,the REST API can be used to query and manipulate the applicationenvironment.

Snapshots provide a detailed picture of a given application at a certainpoint in time. Snapshots usually include call graphs that allow thatenables drilling down to the line of code that may be causingperformance problems. The most common snapshots are transactionsnapshots.

Application server 430 communicates with network server 425, applicationservers 440 and 450, and controller 490. Application server 450 may alsocommunicate with other machines and devices (not illustrated in FIG. 4).Application server 430 may host an application or portions of adistributed application. The host application 432 may be in one of manyplatforms, such as including a Java, PHP, .Net, and Node.JS, beimplemented as a Java virtual machine, or include some other host type.Application server 430 may also include one or more agents 434 (i.e.,“modules”), including a language agent, machine agent, and networkagent, and other software modules. Application server 430 may beimplemented as one server or multiple servers as illustrated in FIG. 4.

Application 432 and other software on application server 430 may beinstrumented using byte code insertion, or byte code instrumentation(BCI), to modify the object code of the application or other software.The instrumented object code may include code used to detect callsreceived by application 432, calls sent by application 432, andcommunicate with agent 434 during execution of the application. BCI mayalso be used to monitor one or more sockets of the application and/orapplication server in order to monitor the socket and capture packetscoming over the socket.

In some embodiments, server 430 may include applications and/or codeother than a virtual machine. For example, servers 430, 440, 450, and460 may each include Java code, .Net code, PHP code, Ruby code, C code,C++ or other binary code to implement applications and process requestsreceived from a remote source. References to a virtual machine withrespect to an application server are intended to be for exemplarypurposes only.

Agents 434 on application server 430 may be installed, downloaded,embedded, or otherwise provided on application server 430. For example,agents 434 may be provided in server 430 by instrumentation of objectcode, downloading the agents to the server, or in some other manner.Agent 434 may be executed to monitor application server 430, monitorapplication 432 running in a virtual machine (or other program language,such as a PHP, .Net, or C program), machine resources, network layerdata, and communicate with byte instrumented code on application server430 and one or more applications on application server 430.

Each of agents 434, 444, 454, and 464 may include one or more agents,such as language agents, machine agents, and network agents. A languageagent may be a type of agent that is suitable to run on a particularhost. Examples of language agents include a Java agent, .Net agent, PHPagent, and other agents. The machine agent may collect data from aparticular machine on which it is installed. A network agent may capturenetwork information, such as data collected from a socket.

Agent 434 may detect operations such as receiving calls and sendingrequests by application server 430, resource usage, and incomingpackets. Agent 434 may receive data, process the data, for example byaggregating data into metrics, and transmit the data and/or metrics tocontroller 490. Agent 434 may perform other operations related tomonitoring applications and application server 430 as discussed herein.For example, agent 434 may identify other applications, share businesstransaction data, aggregate detected runtime data, and other operations.

An agent may operate to monitor a node, tier of nodes, or other entity.A node may be a software program or a hardware component (e.g., memory,processor, and so on). A tier of nodes may include a plurality of nodeswhich may process a similar business transaction, may be located on thesame server, may be associated with each other in some other way, or maynot be associated with each other.

A language agent may be an agent suitable to instrument or modify,collect data from, and reside on a host. The host may be a Java, PHP,.Net, Node.JS, or other type of platform. Language agents may collectflow data as well as data associated with the execution of a particularapplication. The language agent may instrument the lowest level of theapplication to gather the flow data. The flow data may indicate whichtier is communicating with which tier and on which port. In someinstances, the flow data collected from the language agent includes asource IP, a source port, a destination IP, and a destination port. Thelanguage agent may report the application data and call chain data to acontroller. The language agent may report the collected flow dataassociated with a particular application to a network agent.

A network agent may be a standalone agent that resides on the host andcollects network flow group data. The network flow group data mayinclude a source IP, destination port, destination IP, and protocolinformation for network flow received by an application on which networkagent is installed. The network agent may collect data by interceptingand performing packet capture on packets coming in from one or morenetwork interfaces (e.g., so that data generated/received by all theapplications using sockets can be intercepted). The network agent mayreceive flow data from a language agent that is associated withapplications to be monitored. For flows in the flow group data thatmatch flow data provided by the language agent, the network agent rollsup the flow data to determine metrics such as TCP throughput, TCP loss,latency, and bandwidth. The network agent may then report the metrics,flow group data, and call chain data to a controller. The network agentmay also make system calls at an application server to determine systeminformation, such as for example a host status check, a network statuscheck, socket status, and other information.

A machine agent, which may be referred to as an infrastructure agent,may reside on the host and collect information regarding the machinewhich implements the host. A machine agent may collect and generatemetrics from information such as processor usage, memory usage, andother hardware information.

Each of the language agent, network agent, and machine agent may reportdata to the controller. Controller 490 may be implemented as a remoteserver that communicates with agents located on one or more servers ormachines. The controller may receive metrics, call chain data and otherdata, correlate the received data as part of a distributed transaction,and report the correlated data in the context of a distributedapplication implemented by one or more monitored applications andoccurring over one or more monitored networks. The controller mayprovide reports, one or more user interfaces, and other information fora user.

Agent 434 may create a request identifier for a request received byserver 430 (for example, a request received by a client 405 or mobiledevice 415 associated with a user or another source). The requestidentifier may be sent to client 405 or mobile device 415, whicheverdevice sent the request. In embodiments, the request identifier may becreated when data is collected and analyzed for a particular businesstransaction.

Each of application servers 440, 450, and 460 may include an applicationand agents. Each application may run on the corresponding applicationserver. Each of applications 442, 452, and 462 on application servers440-460 may operate similarly to application 432 and perform at least aportion of a distributed business transaction. Agents 444, 454, and 464may monitor applications 442-462, collect and process data at runtime,and communicate with controller 490. The applications 432, 442, 452, and462 may communicate with each other as part of performing a distributedtransaction. Each application may call any application or method ofanother virtual machine.

Asynchronous network machine 470 may engage in asynchronouscommunications with one or more application servers, such as applicationserver 450 and 460. For example, application server 450 may transmitseveral calls or messages to an asynchronous network machine. Ratherthan communicate back to application server 450, the asynchronousnetwork machine may process the messages and eventually provide aresponse, such as a processed message, to application server 460.Because there is no return message from the asynchronous network machineto application server 450, the communications among them areasynchronous.

Data stores 480 and 485 may each be accessed by application servers suchas application server 460. Data store 485 may also be accessed byapplication server 450. Each of data stores 480 and 485 may store data,process data, and return queries received from an application server.Each of data stores 480 and 485 may or may not include an agent.

Controller 490 may control and manage monitoring of businesstransactions distributed over application servers 430-460. In someembodiments, controller 490 may receive application data, including dataassociated with monitoring client requests at client 405 and mobiledevice 415, from data collection server 495. In some embodiments,controller 490 may receive application monitoring data and network datafrom each of agents 412, 419, 434, 444, and 454 (also referred to hereinas “application monitoring agents”). Controller 490 may associateportions of business transaction data, communicate with agents toconfigure collection of data, and provide performance data and reportingthrough an interface. The interface may be viewed as a web-basedinterface viewable by client device 492, which may be a mobile device,client device, or any other platform for viewing an interface providedby controller 490. In some embodiments, a client device 492 may directlycommunicate with controller 490 to view an interface for monitoringdata.

Client device 492 may include any computing device, including a mobiledevice or a client computer such as a desktop, work station or othercomputing device. Client device 492 may communicate with controller 490to create and view a custom interface. In some embodiments, controller490 provides an interface for creating and viewing the custom interfaceas a content page, e.g., a web page, which may be provided to andrendered through a network browser application on client device 492.

Applications 432, 442, 452, and 462 may be any of several types ofapplications. Examples of applications that may implement applications432-462 include a Java, PHP, .Net, Node.JS, and other applications.

(Note that the specifically configured system 500 of FIG. 5and the customized device 200 of FIG. 2 are not meant to be mutuallyexclusive, and the techniques herein may be performed by any suitablyconfigured computing device.)

As noted above, the majority of application performance monitoring (APM)solutions define the rules and configurations for their monitoringagents based on certain predefined logic with no insight into the userapplications being monitored. So, tracking the runtime behavior of anapplication outside its defined scope becomes tedious because doing sowarrants manual intervention and/or additional rules/configurations. Inother words, current APM solutions predetermine the scope of thedefinitions (e.g., the business transaction) with the hope of capturingthe events of interest (e.g., exit calls, exceptions, etc.) within thatscope. If that is not the case, then the scope needs to be configuredmanually.

Automatic Scope Configuration of Monitoring Agents for Tracking MissingEvents at Runtime

The techniques introduced herein allow for the automatic configurationof monitoring agents to trach missing events at runtime. In someaspects, the techniques herein may be used to dynamically adjust thebusiness transaction definitions used by a monitoring agent, either byadding a new business transaction or editing an existing one.

Specifically, according to one or more embodiments described herein, adevice receives, from a monitoring agent that monitors an application,an indication that the monitoring agent did not capture informationregarding a particular event during execution of the application. Thedevice determines that the particular event is of a relevant event typethat should be tracked. The device generates a configuration for themonitoring agent that adjusts a monitoring scope of the monitoring agentso as to capture information regarding the particular event. The devicecauses the monitoring agent to be updated with the configuration,wherein the monitoring agent captures information regarding theparticular event after being updated with the configuration.

Operationally, FIGS. 6A-6D illustrates an example architecture 600 forconfiguring the scope of a monitoring agent to track missing events atruntime, according to various embodiments. As shown in FIG. 6A,architecture 600 may include a monitoring agent 602, such as any of theagents described previously with respect to FIG. 4. In addition,architecture 600 may also include a controller 604 (e.g., controller 490in FIG. 4) that oversees the operation of monitoring agent 602. Invarious embodiments, architecture 600 may also include a scopeconfiguration service 606 in communication with monitoring agent 602 andcontroller 604. As would be appreciated, monitoring agent 602,controller 604, and scope configuration service 606 may be implementedon a singular device or a plurality of devices in communication with oneanother. In the latter case, the plurality of devices may be viewed as asingular device for purposes of implementing the techniques herein.Further, the functionalities of monitoring agent 602, controller 604,and scope configuration service 606 may be combined or omitted, asdesired. In addition, while a single monitoring agent 602 is shown,architecture 600 can be expanded for use with any number of monitoringagents, in further implementations.

To illustrate the teachings herein, assume first that monitoring agent602 as been configured with a set of business transactions to monitorfor the application under scrutiny. Thus, during execution, monitoringagent 602 may capture information regarding various events of theapplication at runtime. In general, an event may be any processing stepor set of processing steps employed by the application during execution.For instance, example events that may be captured by monitoring agent602 may include any or all of the following:

-   -   Exceptions    -   Exit calls    -   Thread handoffs    -   etc.

Thus, during use, monitoring agent 602 may capture information regardingevents of the application, such as those that occur during businesstransactions monitored by monitoring agent 602. Such event informationmay include, for instance, the type of event observed by monitoringagent 602, a timestamp indicative of when the event occurred, a stacktrace for the event, or other such information.

As shown in FIG. 6A, assume that monitoring agent 602 has missed one ormore events during monitoring of the application. In such a case,monitoring agent 602 may send a notification 608 of the missing event(s)to scope configuration service 606. For instance, notification 608 maydenote the type of missed event and other context information regardingthe missed event.

In turn, scope configuration service 606 may determine whether any ofthe missing event(s) indicated by notification 608 should be captured.Indeed, some missed event may not be worth tracking or of a type that isof low interest to the APM user. For instance, while exit call eventsmay be of high relevance to the user, internal thread handoff events maybe of significantly less relevance and can remain uncaptured.

Scope configuration service 606 may employ any number of differentapproaches, to determine whether an event missed by monitoring agent 602should be captured. In some embodiments, scope configuration service 606may rely on user-defined rules or heuristics, to determine whether amissing event should be captured by monitoring agent 602.

In further embodiments, scope configuration service 606 may leveragemachine learning, to determine whether monitoring agent 602 should beconfigured to capture a missing event. In general, machine learning isconcerned with the design and the development of techniques that take asinput empirical data (such as network statistics and performanceindicators), and recognize complex patterns in these data. One verycommon pattern among machine learning techniques is the use of anunderlying model M, whose parameters are optimized for minimizing thecost function associated to M, given the input data. For instance, inthe context of classification, the model M may be a straight line thatseparates the data into two classes (e.g., labels) such that M=a*x+b*y+cand the cost function would be the number of misclassified points. Thelearning process then operates by adjusting the parameters a,b,c suchthat the number of misclassified points is minimal. After thisoptimization phase (or learning phase), the model M can be used veryeasily to classify new data points. Often, M is a statistical model, andthe cost function is inversely proportional to the likelihood of M,given the input data.

In various embodiments, scope configuration service 606 may employ oneor more supervised, unsupervised, or semi-supervised machine learningmodels. Generally, supervised learning entails the use of a training setof data, as noted above, that is used to train the model to apply labelsto the input data. For example, the training data may include samples ofevents that should be captured and labeled as such, as well as samplesof events that should not be captured. On the other end of the spectrumare unsupervised techniques that do not require a training set oflabels. Notably, while a supervised learning model may look forpreviously seen patterns that have been labeled as such, an unsupervisedmodel may instead look to whether there are sudden changes or patternsin the behavior of the metrics. Semi-supervised learning models take amiddle ground approach that uses a greatly reduced set of labeledtraining data.

Example machine learning techniques that scope configuration service 606may employ may include, but are not limited to, nearest neighbor (NN)techniques (e.g., k-NN models, replicator NN models, etc.), statisticaltechniques (e.g., Bayesian networks, etc.), clustering techniques (e.g.,k-means, mean-shift, etc.), neural networks (e.g., reservoir networks,artificial neural networks, etc.), support vector machines (SVMs),logistic or other regression, Markov models or chains, principalcomponent analysis (PCA) (e.g., for linear models), singular valuedecomposition (SVD), multi-layer perceptron (MLP) artificial neuralnetworks (ANNs) (e.g., for non-linear models), replicating reservoirnetworks (e.g., for non-linear models, typically for time series),random forest classification, or the like.

In FIG. 6B, if scope configuration service 606 determines that aparticular missing event should be captured by monitoring agent 602,scope configuration service 606 may then determine the correspondingmonitoring scope to capture this event of interest. For instance, assumethat the missing event is an exit call event. In such a case, scopeconfiguration service 606 may identify the appropriate class #method inthe stack trace of where the exit call was made. In some embodiments,scope configuration service 606 may leverage user-defined rules,heuristics, and/or machine learning, to make this determination. Forinstance, if scope configuration service 606 determines a newconfiguration for monitoring agent 602 and this new configuration doesnot capture the desired event, the machine learning algorithm may adjustits strategy and reconfigure monitoring agent 602 as needed, until thedesired event is captured.

Once scope configuration service 606 has determined the appropriatemonitoring scope to capture a missing event, it may then generate acorresponding configuration 610 for monitoring agent 602 that wouldcause monitoring agent 602 to begin monitoring the application at adifferent scope than previously. To do so, scope configuration service606 may operate in conjunction with controller 604 to maintain a pool ofcurrent configuration for monitoring agent 602, such as the businesstransactions currently being monitored by monitoring agent 602, etc.

In turn, scope configuration service 606 may determine whether theseexisting business transaction definitions or other configurations ofmonitoring agent 602 can be modified to include the determined scopeneeded to capture the missing event, according to various embodiments.If so, scope configuration service 606 may include the modification aspart of configuration 610. Conversely, if an existing businesstransaction or other existing configuration of monitoring agent 602cannot be modified to include the needed scope, scope configurationservice 606 may include a new business transaction definition or otherconfiguration as part of configuration 610.

Once scope configuration service 606 has generated correspondingconfiguration 610, it may send the generated corresponding configuration610 to controller 604. As would be appreciated, controller 604 is thecomponent of architecture 600 primarily responsible for allowing a userto track and troubleshoot events of interest of the application withinthe defined monitored scopes (e.g., business transactions, etc.).

In turn, as shown in FIG. 6C, controller 604 may save configuration 610and push configuration 610 to monitoring agent 602. This may be done atany desired time, such as in response to receiving configuration 610from scope configuration service 606, at a predefined update time, inresponse to a request to do so from a user, or the like. In a furtherembodiment, controller 604 may first seek validation of configuration610 from an expert user, before pushing configuration 610 to monitoringagent 602.

In FIG. 6D, monitoring agent 602 may then apply configuration 610,allowing it to begin capturing the missing event(s) of interest atruntime. For instance, configuration 610 may cause monitoring agent 602to retransform a particular class #method to apply a plain old Javaobject (POJO) interceptor to detect a new business transaction, allowingmonitoring agent 602 to capture the previously missing event.

Once monitoring agent 602 has captured monitoring data 612 from themonitored application, monitoring agent 602 may send monitoring data 612to controller 604. In doing so, controller 604 may provide the collecteddata, including information regarding the previously missing event(s) toa user interface for review (e.g., via client device 492 shown in FIG.4, etc.). As noted, the user may also specify to controller 604 whichevents should be monitored by monitoring agent 602, which can be pushedto scope configuration service 606.

In closing, FIG. 7 illustrates an example simplified procedure forconfiguring the scope of a monitoring agent, in accordance with one ormore embodiments described herein. For example, a non-generic,specifically configured device (e.g., device 200) may perform procedure700 by executing stored instructions (e.g., monitoring process 248). Theprocedure 700 may start at step 705, and continues to step 710, where,as described in greater detail above, the device may receive, from amonitoring agent that monitors an application, an indication that themonitoring agent did not capture information regarding a particularevent during execution of the application (e.g., a ‘missing event’).

At step 715, as detailed above, the device may determine that theparticular event is of a relevant event type that should be tracked. Forinstance, the device may determine that the missing event is an exitcall and should be tracked by the monitoring agent. In variousembodiments, the device may base this determination on user-specifiedrules, heuristics, or even on a determination by a machine learningmodel.

At step 720, the device may generate a configuration for the monitoringagent that adjusts a monitoring scope of the monitoring agent so as tocapture information regarding the particular event. To do so, the devicemay define a new business transaction to be monitored by the monitoringagent or adjust an existing business transaction already being monitoredby the agent.

It should be noted that while certain steps within procedure 700 may beoptional as described above, the steps shown in FIG. 7 are merelyexamples for illustration, and certain other steps may be included orexcluded as desired. Further, while a particular order of the steps isshown, this ordering is merely illustrative, and any suitablearrangement of the steps may be utilized without departing from thescope of the embodiments herein.

The techniques described herein, therefore, provide for the automaticconfiguration of monitoring scope for a monitored application, so as tocapture missing events at runtime. Doing so prevents an expert user fromhaving to identify missing events of interest, determine any correctivemeasures, and implement those measures. Such an approach may be prone toerrors and impose considerable overhead on the expert user.

Illustratively, the techniques described herein may be performed byhardware, software, and/or firmware, such as in accordance with theillustrative monitoring process 248, which may include computerexecutable instructions executed by the processor 220 to performfunctions relating to the techniques described herein, e.g., inconjunction with corresponding processes of other devices in thecomputer network as described herein (e.g., on network agents,controllers, computing devices, servers, etc.).

According to the embodiments herein, a method may comprise: receiving,at a device and from a monitoring agent that monitors an application, anindication that the monitoring agent did not capture informationregarding a particular event during execution of the application;determining, by the device, that the particular event is of a relevantevent type that should be tracked; generating, by the device, aconfiguration for the monitoring agent that adjusts a monitoring scopeof the monitoring agent so as to capture information regarding theparticular event; and causing, by the device, the monitoring agent to beupdated with the configuration, wherein the monitoring agent capturesthe information regarding the particular event after being updated withthe configuration.

In one embodiment, the relevant event type is an exit call. In anotherembodiment, the relevant event type is an exception. In an additionalembodiment, the method further comprises receiving, at the device andfrom a user interface, an indication of the relevant event type thatshould be tracked. In another embodiment, the configuration specifies aclass and method that the monitoring agent is to intercept. In a furtherembodiment, the configuration specifies a new business transaction to bemonitored by the monitoring agent. In yet another embodiment, generatingthe configuration for the monitoring agent comprises using a machinelearning model to generate the configuration. In another embodiment, theindication comprises a timestamp and stack trace associated with theparticular event. In an additional embodiment, the monitoring agent isupdated with the configuration at runtime of the application.

Further, according to the embodiments herein an apparatus is disclosedcomprising: one or more network interfaces; a processor coupled to theone or more network interfaces and configured to execute one or moreprocesses; and a memory configured to store a process that is executableby the processor, the process when executed configured to: receive, froma monitoring agent that monitors an application, an indication that themonitoring agent did not capture information regarding a particularevent during execution of the application; determine that the particularevent is of a relevant event type that should be tracked; generate aconfiguration for the monitoring agent that adjusts a monitoring scopeof the monitoring agent so as to capture information regarding theparticular event; and cause the monitoring agent to be updated with theconfiguration, wherein the monitoring agent captures informationregarding the particular event after being updated with theconfiguration.

While there have been shown and described illustrative embodimentsabove, it is to be understood that various other adaptations andmodifications may be made within the scope of the embodiments herein.For example, while certain embodiments are described herein with respectto certain types of networks in particular, the techniques are notlimited as such and may be used with any computer network, generally, inother embodiments. Moreover, while specific technologies, protocols, andassociated devices have been shown, such as Java, TCP, IP, and so on,other suitable technologies, protocols, and associated devices may beused in accordance with the techniques described above. In addition,while certain devices are shown, and with certain functionality beingperformed on certain devices, other suitable devices and processlocations may be used, accordingly. That is, the embodiments have beenshown and described herein with relation to specific networkconfigurations (orientations, topologies, protocols, terminology,processing locations, etc.). However, the embodiments in their broadersense are not as limited, and may, in fact, be used with other types ofnetworks, protocols, and configurations.

Moreover, while the present disclosure contains many other specifics,these should not be construed as limitations on the scope of anyembodiment or of what may be claimed, but rather as descriptions offeatures that may be specific to particular embodiments of particularembodiments. Certain features that are described in this document in thecontext of separate embodiments can also be implemented in combinationin a single embodiment. Conversely, various features that are describedin the context of a single embodiment can also be implemented inmultiple embodiments separately or in any suitable sub-combination.Further, although features may be described above as acting in certaincombinations and even initially claimed as such, one or more featuresfrom a claimed combination can in some cases be excised from thecombination, and the claimed combination may be directed to asub-combination or variation of a sub-combination.

For instance, while certain aspects of the present disclosure aredescribed in terms of being performed “by a server” or “by acontroller,” those skilled in the art will appreciate that agents of theapplication intelligence platform (e.g., application agents, networkagents, language agents, etc.) may be considered to be extensions of theserver (or controller) operation, and as such, any process stepperformed “by a server” need not be limited to local processing on aspecific server device, unless otherwise specifically noted as such.Furthermore, while certain aspects are described as being performed “byan agent” or by particular types of agents (e.g., application agents,network agents, etc.), the techniques may be generally applied to anysuitable software/hardware configuration (libraries, modules, etc.) aspart of an apparatus or otherwise.

Similarly, while operations are depicted in the drawings in a particularorder, this should not be understood as requiring that such operationsbe performed in the particular order shown or in sequential order, orthat all illustrated operations be performed, to achieve desirableresults. Moreover, the separation of various system components in theembodiments described in the present disclosure should not be understoodas requiring such separation in all embodiments.

The foregoing description has been directed to specific embodiments. Itwill be apparent, however, that other variations and modifications maybe made to the described embodiments, with the attainment of some or allof their advantages.
